We have constructed and tested a device for incubation of individual eggs of fish. We measured the diameter of fertilized and water hardened eggs of vendace (Coregonus albula). Each egg developed in a separate incubator, which was a modified Pasteur pipette. Incubation of 315 eggs resulted in 249 hatched embryos (eleutheroembryos). The technique enabled identification of each eleutheroembryo hatching from a given egg. Example of relationship between external diameter of egg and the length of eleutheroembryo showed potential applications of the technique in studies on fish reproduction biology.
